The two ladies looked super stylish as they spent time together at the star-studded party.
Eva looked stunning in her Victoria Beckham gown which perfectly fitted her petite frame — in no small part thanks to her designer friend — and featured a sheer neck detail.

Victoria also chose a floor-length black gown. Her unusual design featured a keyhole section at the front and at the back, and a zip that ran the length of the skirt.
The mum-of-four wore her hair swept to the side, completing her look with smokey eye makeup and stunning Harry Winston jewels.
Tuesday's event was hosted by Eva, who called upon her famous friends to help raise money for a number of causes, including the victims of the recent Philippines typhoon and BBC's Children in Need.
The charities supported also included the Eva Longoria Foundation, which the actress founded in 2012 to help Latin women through education and entrepreneurship.
The gala was co-hosted by Pixie Lott's model boyfriend Oliver Cheshire, with tickets costing £1,000 and tables from £5,000-£15,000.
Among those attending were Nicole Scherzinger, Victoria, Pixie, Tana Ramsay, Vanessa White and hairdresser Ken Paves (pictured).
Speaking at the event, Desperate Housewives beauty Eva said, "This is our fourth annual Global Gift Gala here in London. We do these all over the world.
"This is a really fun, special event, where we try to unite all the people who ae doing amazing things and all the different programmes to bring awareness and raise funds.
"I love giving so I love it when people send me cards that say they have donated money in my name. That's like my favourite gift to get. It is put to good use instead of being stuck in a closet somewhere."
